In 2.49b, there is a tool called knife or loop cut, selecting edge(s) and pressing K key. Is it changed in 2.5x? I could not find that tool. I am having trouble to model without it. What I have found is Edge-> subdivide.
One more question is, is it possible to rotate the UV’s 90 degree? Is there any option to do it. The only option that I know is, select the UV’s and rotate it with Mouse after pressing R key.
Thanks in advance
